(54) REACTOR FOR CARRYING OUT OF THE HS-1 YACHELD PROCESS

The invention relates to chemical engineering and can be used for exo- and endothermic processes. Known reactor containing a sealed working chamber, made in the form of a cylinder, heat exchangers and a mixer 1. A disadvantage of the known device is the inability to change the heat exchange in different phases of the proceeding reaction, which is essentially the quality of the final product. Closest to the present invention is a reactor containing a section for mixing reagents and a vertical cylindrical reaction chamber equipped in height with outer heat exchange sections installed in several layers {2. This unit is characterized by the ability to stabilize heat transfer throughout the thickness of the liquid layer and regulate the mixing activity of the reacting components, which makes it impossible to obtain maximum performance with high quality of the final product. The purpose of the invention is to improve the control of the process by controlling the heat exchange on each phase of the process. It is possible to conduct the process in any speed required for a given reaction, from slowing down fast-flowing to accelerating slow-flowing chemical reactions. This goal is achieved by the fact that the pilar reaction section is equipped with a cylindrical insert located coaxially and made of heat exchange sections, which are located flush with the outer heat exchange sections. The drawing shows the apparatus, a general view. The reactor contains the reaction section 1, with the lower flaptsa 2 of which

Connect the mixing section 3 with the pipelines 4 and 5 for liquid substances or gas and regulators 6 that enter it. A cylindrical insert 7 fixed on the upper flange 8, at the lower end of which there is a reflector 9 with a ribbed surface of the walls. The working chamber 10 is located between the reaction section 1 and the cylindrical insert 7 and ends with drain pipes 1I with a collector leading the cooking product 12. On the outer surface of the reaction section 1 and on the inner surface of the cylindrical insert 7 there are sections of heat exchangers 13 t21 with inlets 22 of heat carrier and outlet 23. The reactor is equipped with thermal insulation 24. Temperature sharp is controlled by thermocouples.

The reactor operates as follows.

The reacting components through pipelines 4 and 5 and the regulators 6 enter the mixing section 3, where intensive mixing is carried out using the mixer and then the reactor 9, which creates a turbulent motion of substances on the way to the entrance to the working chamber 10. At the same time, heat is exchanged on the surface Mixing chambers and at the entrance to the working chamber using sections of heat exchangers 13-15. The sharply differentiated layer of the reacting liquid in the working chamber for a short time is precisely stabilized in temperature from the two-sided contact of the heat exchangers with a thin layer of the mixture of reacting liquids. The walls of the working chamber are ridged surfaces - for

improve heat transfer. With the help of heat exchange sections 16-21, zones are created with a certain thermal mode, a reasonable process technology.

The proposed reactor ensures the stability of the reaction at any point of the reacting mass of liquid or liquid and gaseous substances, which allows to increase the productivity and quality of the product.
